Abstract
The performance of finite width journal bearings lubricated with micropolar fluids is analysed by using, directly, the finite difference method to solve the generalized three-dimensional Reynolds equation. In this paper, the characteristics of finite journal bearings with micropolar and newtonian fluids in the cases of B/ D = 1.0 and B/D = π 10 are obtained and presented graphically. The analysis reveals that the prominent feature of increasing load capacity and decreasing friction coefficient for micropolar fluids is more pronounced at higher eccentricity ratio and lower width-to-diameter ratio, and the volumetric side flow rate is almost the same for both micropolar and newtonian fluids.
